Specification of Letters Patent.

Patented Dee. `12, 1916.z

Application filed .Tuly 9, 1915. Serial No. 38,975.

To all whom it may concern:

Be it known that we, EMIL JOSSE and VVTLI-IELM Gnwsnclin, both citizensof the Empire of Germany, and residents, respectively, ofBerlin-Lankwitz and of Berlin` Germany, have invented certain new anduseful Improvements in Devices for Condensing and VacuumRroducing, 'ofwhich the following is a specification.

The object of the prosentinveiition is to provide an improved device:for condensing and vacuum producing` The invention has reference tosuch devices in which air and vapor are withdrawn by or with the aid ofvater supplied under pressure through a jet ejector arranged to deliverthe water with the withdrawn air into a circulating tank or system fromwhich the air can escape.

-According to the invention besides the air and uncondensed vapor thewater of condensation is Withdrawn by -a jet ejector of a; circulating'1system. To `ain good results the Water of the circulating system must bccooled. 'Xccording'to our invcntionth'is is done by using the condensingwater as cooling medium.

The accompanying drawingr shows more 0r less diagrammatically anembodiment ot the intention.

a is a surface condenser. Zi is a jot ejector, connected to the air.vapor and condensate outlet' from thev condenser. The jot ejector'discharges air and water through-a discharge-pipe o direct into thecirculating tank (l, so that upon the fatcr and ai'r being dischargedinto the tank. the air will risc and' be liberated at the top as `shownby tho arrows in the drawing. Thel circuli-itineY tank fl is providedwith an orcrllou' y).

f is a. *circulatingf pump for withdrawina water .from the tank (l anddelivering it into the jet'cjcrtor l) so that' water is cauzcd tocirculate continuously throufgh the jot o icctor l) and the tained. Thepipe -for dclivcriug' cooling,r water into the condenser n caters thetaule/l whcrc the pipo is 'tormcd into a coil 71,. ihc cooling'watcrlcarcs the condenser n. bythe tube i. l

Various nnxlilications in thc form shown and described may lic madewithin thcscopc of` the claims without dep'arting f-r'oufthc spirit ofour invention.

What wecl'aim as our invcntimraud dosii'e to secure United StatesLetters Patpressure means and arranged to 'Withdraw air and condensatesiuu'dtaneously from said condenser through a single discharge openingand an open tank in said Wat-er oirculating system whereby air ispermitted to pass oiln and a surface of evapora-tion is provvided.

2. ln a condensing plant the combination of a surface condenser.ci'iolingr means for said. condenser. a water circulation systemiiuiependent ot' .the cooling` means, pressure menus for maintaining?said circulation. the said cooling' lucano being' disposed to cool thewater in sun irculation System. producingr means' in said watercircula-tion Sy?- tcm adjacent to and actuated by Said pressure meansand arranged to withdraw air and condensate simultaneously from saidcondenser through a single discharge opening. an open ieaorroir in thecirculation syS- tem to .rccc're the discharge products of the jet. l

3. In a condensing" plant the combination of a surface condenser,cooling means 'for Said cmidcnscr. a water circulation independent otthc cooling' means. a pressure punip to maintain said circulation. jetprin duringr moans in said water circulation :grstcni adjacentto andartuatcd hy said pressure pump and arranged to withdraw air andcondensate aiuiuli'ancouslv troni 4said condenser through a .winniedischarge opel ingr` and an open rcforvnir in the circulztin sys-tcm toreceive thi` discharge products ot' tlnz jci. thc coolingr inrans being'disposed to cool thc contcnts of said reservoir.

l. ln a windowing: plant thc combination.

of' a surface ruudruscr. cooling moans inclndiugY a pipa` section for'said condenser. a water circulation sjvstcin iiuhpciulent ot thecoolingr nicnas. a pressure pump in said cir- 'culatiou system.

a surface condenser, cooling means for.

and an open reservoir in the circulation system to receive the air andcondensate removed by the jet, the pipe section of said cooling Ineens'passing through said reservoir. l

5. In a condensing plant the combination of n surface condenser, acirculating cooling system for said condenser, a second circulatingsystem entirely independent of the cooling system, a pressure pump and ajet actuated thereby in said second system, a single pipe connectionfrom a point beneath the Water level of the condenser to said jetthrough which all air end condensate must pass when drawn from thecondenser', and 15 an open reservoir in Said second circulating system,said cooling system passing through said reservoir.

In testimony whereof, we have hereunto set oui hands.
